Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.298A>G (p.M100V) alteration is located in exon 4 (coding exon 4) of the MPRIP gene. This alteration results from a A to G substitution at nucleotide position 298, causing the methionine (M) at amino acid position 100 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
